This is a set of two Pro-Line Pre-Mounted 30 Series Trencher 2.8" tires, pre-mounted on Black Desperado rear wheels. These pre-mounts are intended for use on the rear of the Traxxas electric Stampede and Rustler trucks. Pro-Line's world class development team spent several months of research, development and testing to ensure that the Trencher 2.8" tire will perform above and beyond your expectations in any condition that you take your truck. The Trencher tread was designed to have ultimate traction combined with long-lasting durability. Each tire lug is shaped to dig into whatever surface you are running on and is ultra-thick so that it is extremely durable. Whether it is loose or hard-packed dirt, sand, snow, street or gravel the Trencher 2.8" tire is up to the task.
